"Fantastic lover" Pete Doherty

Lindi, 29, feels "guilty" for spending the night with the Babyshambles rocker on June 28 - while he was said to still be dating Kate - but told friends she "had to do it".

A friend of Lindi's told Britain's Sunday Mirror newspaper: "Lindi said, 'I felt like I was cheating on Kate, but I just had to do it.'

"Pete told Lindi he was single. He made her laugh and there was something different about him. She said he was vulnerable and it made her feel protective towardshim. She said the night was fantastic in every way. Pete is a sexy guy and Lindi can see why Kate is with him. It was a very passionate evening."

The pair left London's Crystal nightclub together and spent the night at Pete's friend's Kilburn home.

Lindi claims Pete "charmed" her into bed, but immediately regretted her actions the next morning because supermodel Kate is one of her idols.

The friend added: "Lindi had the post-sex guilt hangover the following morning.

"She really looks up to Kate as one of the best and most beautiful women in the modelling business. But she told me all about her night with Pete and said they had great sex. Lindi said he was very funny and charmed her into bed."

Lindi also reportedly told friends Pete - who was ordered to enter rehab or face jail by a judge last week - has been phoning her, saying he is desperate to see her again.

The source said: "She really seems to be attracted to Pete. She told me she has spoken to him on the phone many times and has agreed to meet him again."
